source: trunk/IPs/systemC/processor/Morpheo/Behavioural/src/Component_port_map.cpp @ 113

Last change on this file since 113 was 113, checked in by rosiere, 15 years ago

1) Add modelsim simulation systemC
2) Modelsim cosimulation systemC / VHDL is not finish !!!! (cf execute_queue and write_unit)
3) Add multi architecture
5) Add template for comparator, multiplier and divider
6) Change Message
Warning) Various test macro have change, many selftest can't compile
